Frequently asked

Why does my cat keep sneezing?

Common causes include upper respiratory infections (often viral), allergens or irritants, and dental disease. Frequent sneezing with discharge, congestion, or appetite loss warrants a vet visit.

Is cat sneezing contagious to other cats?

Viral upper respiratory infections can spread between cats. If you have a multi-cat home and one is sneezing with discharge, separate them and consult your vet.
